A bit of perspective

Your study time: can you find and absorb what you need to play this system well?

Your aims: are you trying to get a playable position? are you trying to
set your opponent problems, so they make a mistake? are you inviting
your opponent to waltz with you blindfold on the edge of a cliff? are
you trying to lure them into unfamiliar territory, or a trap?

Any opening is only as good as the ideas you bring to it. I don't think
I heard much from you about what your ideas were in playing ...b6: what
sort of position do you hope to get to play?

The ideas behind some systems can be pretty straightforward - for
example, I think the Evans Gambit and the French Defence and the Colle
System can be picked up pretty quickly by club players, and the extra
ideas you need as your opponents get better at meeting your new opening
can be added fairly easily. The French Defence in particular often
leads to the same sort of pawn structure (white Pd4 Pe5 vs black Pd5
Pe6), so, even if you don't recognise the exact variation, you can still
have a good idea about the best plans for both sides.

1...b6 is a rarity - you will struggle to find many books to read, or
games to follow. If you look it up in the books, you will find most of
the lines end in +=. The ideas behind the opening are hard to find or
understand: I think it can be best interpreted as a hypermodern defence,
letting White occupy the centre then hoping to get play later, either by
deciding on your own central setup once you have seen what White has
done, or using the centre as a target. I think it ends up as += because
that is hard to do! Also, you aren't going to get the same structures
and ideas in each game, and you are going to lose games that you don't
understand.
